base 10 preferably has opposite ends provided withlongitudinal extensions 11 having anupwards fold 11 a and suitable for insertion inside acorresponding seat 514 of a terminal block 500 (FIG. 10 ) for stable mutual engagement. Thebase 10 can also have, formed therein, first openings 12 (in the example, two in number) that are preferably elongated in the transverse direction Y-Y and suitable for the insertion ofcorresponding teeth 312 of transverse electrical bridge-pieces 300 schematically shown inFIG. 1 . - Each

With this configuration it is possible to insert, in the vertical direction Z-Z, aflat pin 412 of anelectrical device 400 inside the respective seat 112 of thebase 110 of the “U”, thereby preferably achieving at the same time an electrical contact resulting from the elastic reaction of theopposite lugs 122 which, deformed by the insertion of theflat pins 412, react elastically in the transverse direction Y-Y towards the inside of the “U”. - As shown in
FIG. 10 , it is possible to produceterminal blocks 500 that have aninsulating body 510 formed in the manner of askeleton structure 511, the top part of which can include, at the opposite longitudinal ends, arespective turret 512. Preferably, theturrets 512 are arranged opposite each other to define an internallongitudinal seat 513 suitable for housing a conducting part in the form of an “overturned U” 1,2 according to, for example, various embodiments of the present invention. Thelongitudinal extensions inclined seats 514 formed inside theturrets 512. - Above said
seat 513, theturrets 512 also preferably define anopen space 520. From one of thelongitudinal edges 513 a of theseat 513, a dividingwall 521 preferably extends upwards in the vertical direction Z-Z and joins together in the longitudinal direction the inner faces of the twoturrets 512, defining theopen space 520 in the transverse direction Y-Y.

Eachturret 512 preferably has at least one respectivefront side 512 a and at least onerespective flank 512 b with correspondingrespective openings 515 formed therein in the vertical direction Z-Z, for insertion of a tool for operating the spring or screw type means for fixing theelectric wires 3, andopenings 516 in the longitudinal direction Y-Y for insertion of anelectric wire 3. - As shown in
FIGS. 11 to 15 with thesame body 500, it is possible to provide different types of terminal blocks according to the present invention, such as, i) a connector 600 (FIG. 11 ) housing internally a single-body conducting part 1 according to the first embodiment described, and ii) isolators 700 (FIGS. 12,13) containing two conductingparts 2 arranged opposite each other according to the other embodiment described. - The
isolator 700 can, in turn, include i) abody 710 rotating about apin 710 a inserted inside thehole 521 a of the dividingwall 521 and supporting a singlecurved terminal 711 which, rotating inside the seat 112, comes into contact with theelastic lugs 122 of both theelectrical conducting parts 2, closing the circuit, and ii) a body 720 (FIG. 13) provided with two straight flat-pins 721 for insertion, by means of displacement, inside the respective seat 112 of theelectric conducting parts 2. -

Both the fixing devices can be operated by, for example, means of a tool coaxially inserted inside thevertical hole 515 communicating with the exterior. - The vertically open seat situated between the two opposite turrets preferably also allows insertion depthwise of the
auxiliary devices - In addition to the above, the embodiments of the conducting part and terminal block described herein can also result in further significant advantages since, owing to, for example, the presence of the
elastic lugs piece 300 can be formed by a simple flat part since the elastic force required for the electrical connection is already provided by the lugs incorporated in the conductingpart piece 300 does not require any insulating protection since it is embedded within the insulating body of the terminal block by means of the vertical incisions 521 b in the dividingwall 521. - Other embodiments are within the scope and spirit of the invention. For example, features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
- Further, while the description above refers to the invention, the description may include more than one invention.

extending from the longitudinal opposite ends of the front surface, a respective turret, the turrets being arranged facing each other, defining an open space and an inner longitudinal seat, and have a respective inclined seat, the seats being configured to stably house a conducting part in the form of an overturned “U” according to claim 1 .
6. The terminal block according to claim 5 , further comprising a dividing wall that extends upwards from at least one longitudinal edge of the longitudinal seat in the vertical direction, joining together the inner faces of the two turrets in the longitudinal direction and further defining the open space in the transverse direction, the dividing wall comprising a through-hole in the transverse direction and two opposite vertical incisions.
7. The terminal block according to claim 5 , wherein the vertical incisions have a depth configured to isolate a transverse bridge-piece.
8. The terminal block according to claim 5 , wherein each turret has at least one respective front side and at least one respective flank which have, defined therein, respective openings in the vertical direction and in the longitudinal direction that are configured to connect the turrets with the exterior.
9. The terminal block according to claim 5 , wherein the terminal block is configured as a connector that is configured to internally house an electrical conducting part according to claim 1 .
10. The terminal block according to claim 5 , further comprising two conducting parts according to claim 3 housed opposite each other inside the inner longitudinal seat.
11. The terminal block according to claim 10 , further comprising a device with flat contact terminals configured to isolate an electrical line.
12. The terminal block according to claim 11 , wherein the isolating device is configured to rotate about a pin inserted inside the hole of the dividing wall and has a curved flat contact terminal.
13. The terminal block according to claim 11 , wherein the isolating device has flat pins for insertion by rectilinear displacement.
14. The terminal block according to claim 10 , further comprising a protection device with flat pins.
15. The terminal block according to claim 14 , wherein the flat pins are straight for insertion by displacement inside the seats of the conducting part.
16. The terminal block according to claim 14 , wherein the protection device is a fuse holder.
17. The terminal block according to claim 10 , wherein the terminal block is configured as an grounding connector.
18. The terminal block according to claim 17 , further comprising a flat plate suitable for mating with the longitudinal lugs of the electrical conducting part and provided with hook-shaped parts for engagement with a support rail so as to form the ground terminal of the terminal block.
